The data in the table below were obtained for the reaction: Answer the questions based on this graph:
2 BrO2 (aq) + 2 OH⁻ (aq) → BrO3⁻ (aq) + BrO2⁻ (aq) + H2O (l)
Experiment Number | [BrO2] (M) | [OH⁻] (M) | Initial Rate (M/s)
------- | -------- | -------- | --------
1 | 0.060 | 0.030 | 0.0248
2 | 0.020 | 0.030 | 0.00276
3 | 0.020 | 0.090 | 0.00828
Which of the following is correct regarding the overall order of the reaction?
A) the overall order for this reaction is based on the individual order for OH⁻, so it is 2
B) the overall order for this reaction is based on the individual order for BrO2, so it is 3
C) the overall order cannot be determined
D) the overall order is found by subtracting the individual orders for BrO2 and OH⁻, so it is 1 for this reaction
E) the overall order is found by adding the individual orders for BrO2 and OH⁻, so it is 3 for this reaction
